    I am working on setting up Reverse DNS PTR records on my cPanel server but am not getting where I need to. I have the IP addresses delegated to my server by AT&T and a DNS Stuff Reverse DNS lookup tells me there are no PTR records for the IP address. Here is the zone.db file for the IP address:

    ; Modified by Web Host Manager
    ; Zone File for 15.175.12.in-addr.arpa
    $TTL 86400
    @ 14440 IN SOA ns1.digitalpulsehost.net. shane.digitalpulsehost.net. (
    2005063012
    28800
    14440
    3600000
    86400
    )

    14440 IN NS ns1.digitalpulsehost.net.
    14440 IN NS ns2.digitalpulsehost.net.

    139 IN PTR mail.adlmail.com.
    138 IN PTR ems.adlmail.com.
    153 IN PTR mail.idgwi.com.

    When I do a reverse lookup on 12.175.15.139 it gets to my server but my servers says there are no PTR records. Can anyone tell me why? It does get the correct information when I do a "dig -x" on the IP, but this is what I get:

    ; <<>> DiG 9.2.4 <<>> -x 12.175.15.153
    ;; global options: printcmd

    Where does it get that CNAME from? It is not in my zone files.

    Have you been able to get this working? I'm having occasional reverse DNS trouble, myself.
